I am currently off contract with unlimited data month to month. Since I would like to keep unlimited and stay month to month, plan to buy HTC DNA full price. I checked into Amazon Wireless which is about $40 cheaper than buying it from Verizon, but on emailing Amazon, they make it seem like I would have to go to Verizon to get the SIM card anyway and that if travelling internationally, I would have to get GSM card from Verizon. Seems like it would be worth the extra $40 just to buy the phone full price from Verizon, have them activate from the get go, transfer my insurance, and give me a GSM SIM for future travel on the spot. Any thoughts? Has anyone had experience activating on Verizon, a phone bought through Amazon? I am worried that somehow buying from a 3rd party will get me second class treatment from Verizon. Thanks in advance!
